The suction pipe 51 is located behind the trim of the middle cutter 22. In the embodiment, the branches and leaves to be trimmed firstly extend into the front side cutter 21 from gaps among a plurality of spray pipes at the inlet of the housing 5 or below the spray pipes for trimming, the branches and leaves trimmed by the front side cutter 21 rapidly flow into the middle cutter 22 for further crushing under the combined action of the inertia of the branches and leaves, the branches and leaves crushed by the middle cutter 22 rapidly discharge from the outlet under the combined action of the inertia of the branches and leaves, the air jet flow and the air suction flow, and are further conveyed into the collecting device.
As shown in fig. 8, the gas injection end of the high pressure gas injection mechanism 8 is lower than the highest point of the suction pipe 51, and the end surface of the gas injection end of the high pressure gas injection mechanism 8 is inclined inward of the housing 5 to prevent the high pressure gas injected from the gas injection end of the high pressure gas injection mechanism 8 from flowing outward of the housing 5. The end surface of the air injection end of the high-pressure air injection mechanism 8 is inclined towards the interior of the housing 5, so that high-pressure air injected from the air injection end of the high-pressure air injection mechanism 8 flows only towards the back of trimming and upwards, and the high-pressure air is prevented from flowing towards the exterior of the housing 5 to drive branches and leaves in the housing 5 to flow outwards. In this embodiment, the gas lances 82 are L-shaped. The high-pressure gas in the gas injection pipe 82 flows in the horizontal direction and is injected from the gas injection ports. Since the gas ejection port is inclined toward the inside of the housing 5 (i.e., obliquely upward), a part of the high-pressure gas ejected from the gas ejection port gradually flows obliquely upward after flowing in the horizontal direction for a certain distance.
As shown in fig. 7, the air injection end of the high-pressure air injection mechanism 8 is flush with the rotary cutting surface 200 of the cutter 2 or lower than the rotary cutting surface 200 of the cutter 2, and the air injection flow injected by the air injection end of the high-pressure air injection mechanism 8 forms a high-speed air curtain for preventing the trimmed and broken branches and leaves from falling out of the housing 5 at the rotary cutting surface 200 of the cutter 2 or below the rotary cutting surface 200. In this embodiment, the plurality of sets of cutters 2 are arranged along the trimming direction, and the initial cutting side of the rotary cutting surface of the cutter 2 is inclined toward the surface 100 to be trimmed of the hedge, so that the initial cutting sides of the plurality of sets of cutters 2 are located on the same plane, and the surface 100 to be trimmed of the hedge is trimmed in multiple levels by the blades of the plurality of sets of cutters 2 along the trimming direction. The initial cutting side of the rotary cutting surface of the tool 2 is below or flush with the air jets. The air jet stream ejected through the air jet port drives the pruned branches and leaves to flow toward the suction pipe 51 along the pruning direction.
The flow rate of the high-pressure gas supply device is 20-50% of the flow rate of the suction device. If the flow of the high-pressure gas supply device is lower than 20% of the flow of the suction device, the flow velocity and the dynamic pressure of the gas sprayed by the gas spraying pipe 82 are low, the capability of blowing the branches and leaves to the effective suction area 300 is lost, and the phenomenon that the branches and leaves fall out of the housing 5 is caused; if the flow rate of the high-pressure gas supply device is higher than 50% of the flow rate of the suction device, the gas ejected from the gas ejecting pipe 82 cannot be completely sucked by the suction gas flow at the suction pipe 51, and the unabsorbed high-pressure gas overflows out of the housing 5, so that part of branches and leaves are carried out of the housing 5. In this embodiment, the high-pressure gas supply means includes a blower. The suction device comprises a suction fan.
